Load wires now hot

[str1der]

Hi everyone DIYer here with a weird situation. Have 2 two gang switch in a bathroom. One for the vanity lights the other for the exhaust. Pretty standard stuff. This is a house built 12 years ago. Everything worked fine until a week ago when the lights and fan would no longer turn on. The box has all the grounds and the white neutrals combined. It was wired with 3 black wires, one line shared between the switches and two for the loads. I thought maybe the switches went bad but what I discovered is that some how all 3 black wires are now hot. No other electrical work has been done lately. Any idea what would have caused this?

Only other clue I have is according to my kids the lights stopped working 2 weeks ago (don't know about the fan) then they worked again for a week but back to not working.

Thanks

Anyone have a suggestion?

I think the best idea, assuming all connections are tight, is to get an electrician in to do some testing.

How did you test all blacks were hot?

How did you test all blacks were hot?

I used a light up tester first then put a meter on them
